Data from 141 tenth-acre plots defoliated by a complex of looper species were summarized and analyzed using discriminant analysis. We found certain variables consistently associated with the status of trees as being live or dead (species, site quality, and aspect). Mortality was more likely among species in insect-preferred food classes, on better sites, and on north or northeast aspects. Classification of dead trees was more effective than for live trees. For. Sci. 36(3):831-441.
